Hello. I just bought a lovely 2002 Galant Auto 2.5, V6 on Ebay. I'm no expert but I liked the look and it has low mileage and good reviews. However, despite the new MOT, it has the engine management light stuck on. The seller was honest with me and didn't want to spend any more money on it. His garage detected a faulty sensor marked - bank 2, sensor 1. Does anyone know what this is and how to get one? Sally Ash.
